Hi Ian, I am happy to have found your blog as I usually get northern hemisphere sky info and try to found out if I can observe the same event here in Melbourne. May I ask if Mars, Saturn n Spica on 14 August can be seen by naked eyes? Thanks!

Yes, Mars, Saturn and Spica are all easily visible to the unaided eye, even with reasonable levels of light pollution.

The view from Adelaide will be similar to the view everywhere else in Australia at the equivalent local time. There will be some minor differences in elevation but not enough to make a real difference.

Occultations and eclipses will be different though, as those are very latitude dependent. But I ususally give local descriptions for them.
